Operation and Maintenance Manual

Commissioning

The high-pressure hoses and all couplings, fit-

tings and connections must be checked for integ-

rity and cleaned if necessary before each start-up.

Dirt particles in the hydraulic system lead to mal-

functions and breakdowns. The hydraulic hoses

are to be designed with a large radius so that there

is no risk of accidents. Do not kink, step on, drive

over or damage mechanically.

The Hydraulic Pump must not be operated with-

out connected hoses and hydraulic torque tools!

NOTE!

Check the oil level in the

sight glass.

The correct oil level must

be displayed in the area

between the maximum

and minimum mark.

If necessary, the hydraulic

oil (grade, see 1. technical

data ) can be refilled after

removing the bolt con-

nection (5).

1. Connect the hydraulic hoses of the hydraulic wrench to

the LEVA Hydraulic Pump (K), see also connection diagram,

point 9, page 10.

It is particularly important to ensure that all couplings are fully

and securely coupled so that no hydraulic oil escapes and the

oil flow is not impaired.

2. Connect remote control (F)

3. Important safety instructions

The hydraulic hoses must be provided in pairs with

plug-in coupling and plug-in nipple, so that the

forward (pressure) and return are unmistakably

applied to the piston or rod side of the hydraulic

cylinder of the hydraulic wrench.

If there is an interruption in the return line, a large

excess pressure on the rod side of the hydraulic

cylinder can form, which can destroy the hydrau-

lic wrench and cause serious physical damage to

people.

In general, when creating bolting connections, the

manufacturers instructions for use of the wrench

must be given equal priority and the regulations

or specifications of the corresponding construc-

tion must also be followed with priority.

Before bolting with the LEVA Hydraulic Pump

a function check with max. 100 bar operating

pressure (procedure see point 4 and 4.1) must be

carried out.
